In this stage of pregnancy is common to feel back pain, epecially in the lower back, but it can even reach thighs and buttocks. These annoyances are caused by the so called sciatica, due to the change in the gravity centre. It’s a common symptom and can be avoided by exercising and stretching the column. It’s advisable to practice yoga, to strengthen the muscles and the vertebral column. You can also use a hot water bottle to relieve the pain.

Some pregnant women suffer from the Carpal tunnel syndrome, which is the loss of sensitivity and a tingling sensation in fingers, hands and wrists. It’s due to the increase in fluid retention. While laying, certain areas of the body get swollen, including the wrists, and when the pressure on the tunnel increases, some nerves get pinched, provoking a prickling sensation and sleepiness of the area. The best way to avoid it is trying to find a good position and doing exercises, so that the fluid retention decreases.

Many women recommend performing massages on the perineum area, to avoid the vaginal tearing during birth. If you feel comfortable with this, you can start getting information about how you need to carry them out and start practicing.

Fetal development 33 weeks

During this week, your child is likely to be facing down, a position in which he will remain until labour. By touching your belly, you are able to distinguish between his back, knees or feet. You feel his movements, such as hits and kicks, because now he is too big and cannot move freely inside the womb.

The brain of the baby starts to work: there’s an every time higher quantity of neuronal connections. Even though there’s activity ever since the beginning, it will be at the end of the maturation when the brain will present the highest rate of activity. The end of the maturation takes place during the first stages of infancy.

At the end of this week, your soon will be 43 cm long and will weight 1,980 grams on average. If the weight of your child is located between 1,500 and 2,600 grams, don’t worry, they are also considered normal values.
